论文摘要
我们通过将Mott Transition系与化学冻结的QCD相图(GBU)方法讨论了QCD相图中对光簇产生的中等影响。我们发现,在LHC光簇丰度提供的最高能量的重合离子碰撞中,由于bary型密度低,应遵循统计模型。在核碎裂区域的低能量下,冻结会干扰液态气相变,自养和保利的阻塞效应很重要。在中间能量,Hades,公平和NICA实验可以提供新的信息。 GBU方法为在该能量领域中奇怪的强子生产提供了新的见解,以解释“喇叭”效应。
We discuss medium effects on light cluster production in the QCD phase diagram within a generalized Beth-Uhlenbeck (GBU) approach by relating Mott transition lines to those for chemical freeze-out. We find that in heavy-ion collisions at highest energies provided by the LHC light cluster abundances should follow the statistical model because of low baryon densities. At low energies in the nuclear fragmentation region, where the freeze-out interferes with the liquid-gas phase transition, selfenergy and Pauli blocking effects are important. At intermediate energies the HADES, FAIR and NICA experiments can give new information. The GBU approach provides new insights to strange hadron production in this energy domain for explaining the "horn" effects.
